AI Technical Summary
During the transportation process, existing dump trucks are prone to failure of the fixed mine bucket due to impact force or inertia forces, resulting in mine leakage accidents; during the mining reversal, due to unbalanced ore loading and uneven tracks, the mine bucket is prone to flip in unfavorable directions, increasing the labor intensity of manual flip and posing safety hazards.
A dump truck was designed, with lock blocks and lock grooves on both sides of the mine bucket. Two sets of lock plates were arranged on both sides of the mine frame. The first set of lock plates formed a lock groove with the lock block, and the second set of lock plates cooperated with the side where the lock block did not form a lock groove to enhance the fixed stability of the mine bucket, and resist the turn of the mine bucket through the second set of lock plates, ensuring that the mine bucket can only flip in the direction of the mine bucket or remain vertical.
It effectively enhances the fixed stability of the mine bucket during transportation and reduces the occurrence of mine discharge accidents; during the mine turnover process, the safe flip of the mine bucket is ensured, the labor intensity of manual flip is reduced, and the safety and efficiency of the mine turnover are improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ore transport vehicles, in particular to a dump bucket type ore transport vehicle. Background Art
[0002] The tipping bucket mine car includes a bucket, a mine car frame and wheels. The wheels are installed under the mine car frame for transportation. The bucket is placed on the turning groove of the mine car frame by the turning wheels fixed on the bucket, and then fixed in the locking groove of the bucket by a set of locking plates installed on both sides of the mine car frame. When dumping the ore, open the locking plates stuck on both sides of the mine car frame, and the bucket can be dumped on the turning groove by the turning wheels. This mine car is widely used in mines with rail transportation.
[0003] Mine car transportation is basically connected in series to form a car group and transported by locomotive traction. When the locomotive starts and stops, the mine cars will pull and collide with each other, which will generate a large forward impulse or inertia force generated by sudden stop. This may cause the locking plates on both sides of the mine car frame and the locking groove of the mine bucket to loosen, leaving the mine bucket in an unfixed state. Coupled with the shaking during transportation, the mine bucket will flip over immediately. This causes ore leakage accidents during transportation, which often occurs during actual use. At the same time, during the ore pouring process, whether it is manual or mechanical ore pouring, the locking plates on both sides of the mine car frame must be opened before pouring. However, due to the imbalance of ore loading and the unevenness of the track, after opening the locking plates, some ore buckets will flip in one direction in a natural state. If the flipping direction is in the direction of the ore bin, it is conducive to the ore pouring operation, but if the flipping direction is in the opposite direction of the ore bin, when the ore is manually poured, the labor intensity of manual flipping will increase, and the sudden flipping will also cause certain safety hazards, which is not conducive to the ore pouring operation. When a curved track ore dumper is used to dump ore, if the ore buckets of multiple ore cars lean toward the tipping rod before the dumping starts, the starting torque of the mechanical tipping will increase many times, which may cause the dumping to fail and affect the dumping efficiency. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS
[0016] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on the structures shown in these drawings without paying creative work.
[0017] Figure 1 It is a top view of the bucket-type mining car of the utility model.
[0018] In the figure: 1-ore bucket, 2-ore car frame, 3-locking block, 4-first set of locking plates, 5-second set of locking plates, 6-turning wheel, 7-turning groove.
[0019] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0020] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0022] The utility model embodiment discloses a dump bucket type mining car, such as Figure 1 As shown, including:
[0023] Ore bucket 1, ore car frame 2 and wheels;
[0024] The wheels are installed under the mine car frame 2 to realize transportation, and the ore bucket 1 is placed on the turning groove 7 of the mine car frame 2 by the turning wheel 6 fixed on the ore bucket 1;
[0025] Locking blocks 3 are arranged on both sides of the ore bucket 1, and locking grooves are formed between the locking blocks 3;
[0026] Two groups of locking plates are respectively arranged on both sides of the mine car frame 2. The first group of locking plates 4 cooperate with the locking groove formed between the locking block 3, and the second group of locking plates 5 cooperate with the side of the locking block 3 where the locking groove is not formed, so as to fix the ore bucket 1 on the mine car frame 2.
[0027] In one embodiment of the present invention, the first set of locking plates 4 arranged on both sides of the mining vehicle frame 2 are located at the center line of the mining bucket 1 .
[0028] In one embodiment of the present invention, the second set of locking pieces 5 arranged on both sides of the mining vehicle frame 2 are respectively located on both sides of the center line of the mining bucket 1 .
[0029] In one embodiment of the utility model, the second group of locking pieces 5 arranged on both sides of the mining vehicle frame 2 are arranged symmetrically with respect to the midpoint of the center line of the mining bucket 1 .
[0030] When the utility model dump bucket mine car is in use, the possibility of the two sets of locking plates and the locking groove being loosened at the same time due to impact force or inertia force is very small, which greatly increases the stability of the ore bucket 1 fixed to the mine car frame 2. When the mine car 1 is dumping ore, whether it is dumping ore manually or mechanically, the second set of locking plates 5 on the side relatively farther from the ore bin is kept in a locked state, and the second set of locking plates 5 on the side relatively closer to the ore bin and the two first sets of locking plates 4 are opened. Because the second set of locking plates 5 on the side relatively farther from the ore bin supports the ore bucket 1 to flip to the opposite side of the ore bin, the ore bucket 1 can only flip to the ore bin or remain in an upright state in a natural state, and it can be safely operated regardless of manual or mechanical ore dumping.
[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
